Question about Whirlpool Washing Machines
"F11" is a Serial Communications error between the Central Control Unit (CCU) and Motor Control Unit (MCU). The CCU is the main computer for the washer and is located directly behind the wash tub. The MCU is the Drive Motor Control board and is located in the rear of the washer adjacent to the Drive Motor on the left-hand side (facing from the rear with the back panel removed). The wiring harness can also cause the error, but it is not as common a problem.
Whirlpool is the manufacturer of both model washers and recommends the following troubleshooting advice. Remove the top panel of the washer by removing the three screws holding it in place in the rear. Once the screws are removed, the panel slides back, then off. Remove the rear panel of the washer for access to the drive motor and MCU. Now check the following:
- Check the wire harness connections between the CCU, the MCU and Drive Motor. Make sure all connections are attached and making good contact. Check for any broken wires or connector pins.
- Check the Drive Motor to see if it free spins and that the belt is still attached and not slipping. If the motor is seized, replace it. If the belt is broken or worn, replace it as well.
- Check the MCU. Connector 1 is the Serial Communications Link between the MCU and CCU. Connector 2 is the connector to the drive motor. Resistance checks across pins 1, 2, & 3 are the motor windings. Connector 3 is the power supply - 120VAC should be read across pins 1 and 2 with the door in the locked position. NOTE: The connectors are read 1, 2, and 3 from the bottom to the top with the MCU installed.
- Check the CCU. Verify connectors 7 and 11 are properly installed. Facing from the front of the washer, connector 7 is the 4th connector from the RIGHT along the front. This is MCU Power. Connector 11 is the Serial Communications link from the CCU to the MCU and is located along the left hand side of the CCU (the connectors are numbered 11 through 14 back to front).
- Check the Drive Motor. Remove the connector and perform resistance checks on the motor connector pins. Readings across pins 1 to 2, 2 to 3 and 1 to 3 should read 6 ohms.
In most cases this is an indication of a failed CCU. This is an easy repair that the average do-it-yourselfer can accomplish on their own. If the washer is still under a warranty, parts and labor would be covered. With no warranty, a replacement parts will vary in price depending on where you get them. There are several good websites available that you can order parts on line and have shipped directly to you.
NOTE: Remove all the connectors from the CCU ONE AT A TIME and reconnect to see if the error code goes away BEFORE you decide to purchase a new one. It is not common, but sometimes a flaky connection can generate error codes.

You have a problem with your soap dispenser. This has been a very common problem. You need to order W10161052 Actuator, W10157886 Dispenser, 8183186 Actuator Motor. Put these new parts in and you will be fixed.

Here are the steps to unlocking the door manually
2.remove bottom panel
3.Reach up along the inside of the front panel and locate the botttom of the door latch assembly
4.Located on the bottom of the door latch assembly is a tear dropped shaped tab
5. Gently pull down on the tab about a 1/4 inch or until a click is heard.
6. You may now open the door.
This code means the door lock mechanism has failed or the central control unit has failed. Replace the door lock mech. first. This should fix the problem. (before replacing anything make sure there is no obstruction around the switch or in the switch.) After the machine has been unplugged it may fix itself. if not replace door lock mech.

Sud= The unit has sensed there is too many suds in the unit it will
flush and pump out for 5 min and restart on its own..This is caused by
too much soap use..
From the book :
If too much detergent was used:
—Run the unit through a Rinse/Spin cycle.
—Run a Normal cycle without adding any detergent.
This should clear the unit of the excess detergent.
1. Check the drain hose and make sure it is not plugged
2. Unplug washer or disconnect power.
3. Check wire harness connections to the drain pump,
pressure switch, and Central Control Unit (CCU).
4. Check/clean drain pump filter of foreign objects.
5. Plug in washer or reconnect power.
6. Check drain pump.
7. Check the pressure switch.
8. Verify CCU operation by running a Diagnostic test or any

An "F-11" error code on a Whirlpool Duet could cause your washer to become inoperable and stop in the middle of a load. The cause of the problem could be a number of things and may require new parts.
F11 can mean anything from motor to motor control board to ccu board to wiring harness connecting ccu to mcu to motor.
The "F-11" code could appear with the dash or without the dash on the LCD screen. Be aware that there is also an "F-H" code that could look similar to the "F-11" code. Listen for 11 beeps to go along with the error code's first appearance.
The error means that there is no communication between the "Motor Control Unit" and the "Central Control Unit." This means that any operation selected like "Pre-wash" or "Large Load" cannot be sent to the motor for the washer to operate.
Open up the washer panel to check the wire connections between the two units. If any plugs are loose or unplugged, reconnect them. Check to make sure none of the wires are stripped, rusty or broken off. After you reconnect the wires, rerun the washer to see if the error appears again.
If you do not know or understand the inside components of your Whirlpool washer, leave the job to a professional. Contact the store where you purchased the washer or Whirlpool customer service directly.
Please get back to us if you have further query else please accept the suggestion.
